To all whom z't may concer/n.'

Be it known that l, FRANK H. Wma, a

and State of New York, have invented certain new and useful Improvements in a Baiile Bricl :of which the following is a specification.

This invention relates to the construction of arches for locomotive furnaces of the steam type and has for its principal object to provide a simple and eiiicient baiile brick which may be easily and quickly placed in its proper position when forming the arch and when in its proper position will lit snugly against its supports, usually the water or air bars.

In the arches now commonly in use in locomotive furnaces it has been found from experience that the baille bricks soon become broken or otherwise injured because of the continuous jarring to the locomotive which is imparted to the bricks and because of the fact that they are not rigidly mounted in a substantial manner, these bricks soon be'- come cracked or utterly demolished and thus the eiliciency of the'arch is greatly reduced.l

Another object of the invention is to pro- ,vide -a baille brick to be used in constructing the sides of the arch adjacent the furnace walls which bricks may be easily attached to the'wall and detachedvtherefrom when so desired.

.- In the drawing Figure 1 is a sectional view taken through one wall of a furnace showin a fragmentary elevational viewof one en ofthe arch,

Figure 2 is a top plan view of the'structure disclosed in Figure 1,

Figure 3 is a section taken on the line 3-3 of Figure 1 looking in the direction'of the arrow,

Figure 4 is a perspective view of the central. bame bricks and A Figure 5 is a perspective view of the side baille bricks.-

Referring to the drawing in detail it will be seen tha-t 1 designates aside wall cfa-giurnace while the bars 2 extending in a slibstnn-l tially parallel line thereto, represent' 'water bars or air bars Jfer the purpose of cooling the 'baffle bricks and also acting as a support therefor. lThe arch is 4fori'ned by u pas which are placed plurality ci battle between the bars 2. the irirnace as is w central barile cl the side walls 1 of kncwn in the art. shawn in the present illustration of the invention are indicated by the numeral 3. These baille bricks may be of any preferred shape and as here shown are rectangular in top plan and are provided in their ends with channels 4. As shown to advantage in Figures 3 and 4 these channels 4 are deeper at one end than at the other. The deeper parts 5 of the channel are diagonally arranged in relation to each other as clearly seenin Figure 3. Thus the central baille brick disclosed in Figure 3 may be removed by rotating the same in a clockwise direction bringing the deeper portion 5 of the channels 4 in engagement with the bar 2. When in this position the central bricks 3 may be easily removed as will be understood by those skilled in the art.

'Il-he side bricks 6 disclosed to advantage in Figure 5 are each provided witha channel 7 at one end and a bayonet slot'in the other end. The flanges 9 provided on the sides of the bricks 6 are oppositely disposed s'othat when the bricks are placed together there will be a locking engagement with each other@ indicated by the dotted lines inFigure 2. The bricks 6 are positioned in place by placing the channels 7 thereof in engagement with the bars 2 and the lugs 10 on the furnace wall 1 in'engagement with the entrance to the bayonet slot 8. When the l is in the slot the brick will then be pus ed so as to place tlie lug or the brick in Such a position that the lug will be situated at the end of the slot opposite its openends, said channels being deeper at one of their ends and said deeper portions being diagonally disposed in relation tothe bricks, and a plurality of bricks situated between the bars and the Walls, lugs provided on the walls, said latter mentioned bricks each provided with a channel in one end for e gaging one of the bars and a bayonet slot in/its ot er end for engaging one of thelugs.

ln testimony whereof l a my signature in presence di two witnesses.
